Maps & Technical Data

NI 43-101 Technical Report (April 2020).

History

Gold and silver were discovered at Los Reyes by the Spanish in the late 1700s and mining occurred in the area for over 150 years up until the 1950s. The Guadalupe de los Reyes underground mine opened in the late 1800s and to date is the most significant source of gold production in the district. It is estimated to have produced 500-600,000 oz of gold and 40M oz of silver at reported grades of +10 g/t Au and +500 g/t Ag.

From the 1950s through the 1980s there was limited activity in the Los Reyes area other than mostly exploration reconnaissance studies. Modern drilling began at the Los Reyes area in the 1990s and was targeted at defining shallow and lower-grade gold-silver mineralization in areas surrounding the Los Reyes underground operations. Since that time, over 50,000 meters of RC and core drilling have been completed within the current project boundaries resulting in extensive area-wide resource data.

Why Los Reyes?

Los Reyes hosts well-advanced:
Gold resources of:
633kozs
Measured & Indicated
179kozs
Inferred
Silver resources of:
16,604kozs
Measured & Indicated
6,831kozs
Inferred
Established and operating in Sinaloa, Mexico with additional early stage gold/silver opportunities

Exploration Upside with Production Optionality

Los Reyes was on-track to become a heap leach mine in 1998...
When gold prices dropped the project was mothballed.

Current pit-constrained resource areas - open on strike and at depth
Additional mineralized zones - 8 to 10 new high-grade underexplored surface discoveries for drill testing
Untested new claim blocks added to project have yet to be explored
Direct access to roads, power, abundant water, and local labor force
Amenable to simple open pit heap leach mining
Tens of millions already spent in exploration & engineering studies, 8 open pit deposits delineated
Holds great upside potential for both resource expansion, along strike, down dip, at depth, and in new areas
Experienced management team very familiar with the region and open pit heap leach operations; local team already in place

Concession Boundary

Exceptional exploration upside with current and new targets

  • 8 to 10 new high grade underexplored surface discoveries for drill testing
  • Untested new claim blocks added to project yet to have any exploration

Consolidation opportunity and partnership

  • Potential consolidation of assets and operations into mid-tier producer at a later date
  • Option to acquire Vista Gold’s 2% NSRs (surface and underground) and a 49% back-in right

Exploration Potential

STRATEGY IS TO FOLLOW THE DEFINED STRUCTURES AND DRILL ALONG STRIKE, DOWN-DIP, AND NEW TARGET AREAS IDENTIFIED THROUGH MAPPING AND TRENCHING

OUR CURRENT DRILL SUMMARY

The Path Forward

1 Upgrade Resource

Upgrade 7.1 million tonnes of current Inferred resource to the Measured and Indicated category

  1. Approximately 2,000 metres of surface trenching – COMPLETED
  2. Approximately 3,000 metres of drilling in 15 to 20 shallow holes  – ONGOING
2 Expand Resource

Add new gold and silver ounces by drilling along strike and down dip adjacent to the existing pit-constrained resource areas

  1. Approximately 1,500 metres of surface trenching – COMPLETED
  2. Approximately 5,000 metres of drilling with some drill holes reaching 250 metres in depth – ONGOING
3 Logistics

Define the potential to add new gold and silver ounces in unexplored areas where existing data and new mapping data confirm the target potential

  1. Approximately 3,500 metres of surface trenching – ONGOING
  2. Approximately 7,000 metres of drilling with some drill holes reaching 400 to 500 metres in depth – ONGOING

Mapping and Sampling

  • A new detailed base geologic map is being prepared for the entire Los Reyes concession area
  • Surface mapping of the various rock types, alterations, geologic structures and other physical features
  • Log and analyze 13,000 metres of core contained in 89 drill holes in Prime’s core shack in Hermosillo
  • New regional soil and rock chip sampling and assaying will be completed to acquire fresh data

Schedule and Logistics

  • The program will work through the rainy season
  • Mapping and core logging activity is ongoing
  • The initial trench sampling is completed
  • Currently this phase of exploration is expected to be active through Q2 2021

Metallurgical Test Work

  • Past metallurgical tests show that both heap leach and milling/CIL recovery are viable options
  • The drill and channel sample material sent to the assay lab will be analyzed for cyanide solubility using bottle roll and similar testing in order to build a stronger database of recovery data across the project
